I have received a voucher which I can redeem for Google adwords. While signing for an adword account, google asks for my credit card details. (They say, its for charging any additional costs above my amount) I do not want to pay anything above the voucher amount, but, cannot proceed without putting in my credit card details. Have sent them a mail a couple of days back. Have not received any responce as yet. Any suggestions?
They need to take your card details, no way around that. Just set your max monthly budget to whatever you want to pay.
